Asbestos is a naturally occurring mineral that was used widely in construction in the past due to its heat resistance, durability, and sound absorption properties. However, when asbestos-containing materials are damaged or disturbed, they can release tiny fibers that can be inhaled and cause serious health problems, including lung cancer, mesothelioma, and asbestosis.

Asbestos was widely used in the construction industry until the 1990s when its harmful effects became widely known. Today, it is illegal to use asbestos in new construction, but many older buildings still contain asbestos-containing materials.
